PURPOSE: A method for supplying a carburizing material in a ladle furnace is provided to prevent reaction between a carburizing material and slag by dipping an injection tube into molten steel in a ladle furnace and injecting inactive gas to supply the carburizing material. CONSTITUTION: A method for supplying a carburizing material in a ladle furnace comprises the steps of: preparing a carburizing material(113) having a size to be transferred by transfer gas(111), arranging an injection tube(110) into a ladle furnace(100), and injecting transfer gas excluding oxygen and nitrogen to transfer the carburizing material. When arranging the injection tube, the injection tube passes through a slag layer(107) formed on the surface of molten steel(M) in the ladle furnace and an outlet(119) of the injection tube is dipped in the molten steel.
